PROCESSING OF AZIMUTHAL RESISTIVITY DATA IN A RESISTIVITY GRADIENT |
摘要 |
A method for increasing sensitivity in a measurement of at least one of magnitude and direction of resistivity in a subsurface material, the method including: performing a first set of measurements of resistivity of the subsurface material using a first logging instrument; constructing a model of a background signal using the first set of measurements; calculating a predicted response of a second logging instrument to the model of the background signal; performing a second set of measurements of at least one of magnitude and direction of resistivity of the subsurface material using the second logging instrument; deriving a second logging instrument response from the second set of measurements; and subtracting the predicted response from the second logging instrument response to produce a corrected response that has greater sensitivity than the second logging instrument response. |
